Twitter goes down during Biz Stone's SXSW panel

Right now Biz Stone is sitting on a stage in front of a massive audience at SXSW, talking about the collective organizing power of Twitter. Little does he know Twitter.com has mysteriously gone down.

Everyone in the audience is hitting refresh on their iPads and laptops frantically because -- #21stcenturyalanismorissetteironies -- the questions to Biz are supposed to be posed over Twitter. Using the hashtag #askbiz.

It's been the SXSW M.O., allowing interviewers to pick and choose softball questions from the audience via tweets instead of fielding anything challenging.

The presenter keeps saying, "In just a second we'll get to questions from the audience." With Twitter broken there's no way to inform him that Twitter is broken and there will be no audience questions. #Inception

No word from Twitter yet on what's caused the outtage. We'll update this as the panel progresses.
